The best thing about this recipe is you can use virtually any cut of beef. If you want to splurge? Go for the best cuts and don't worry about the pounding. If you need to save a few buck? Go for what's on sale and just make sure you pound it out well and cut it thin. To be honest I've done both and both come out wonderful!
Wow, this was really good. I used grass fed milanesa (it was already really thin when I got it from Whole Foods so I didn't pound it). Added garlic powder, paprika and onion powder to the bread crumbs for a little more kick and used spelt flour to coat. Best Milanesa, or for that matter, breaded meat I've ever had.
